Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

16-Bit Floating-Point Square-Root Algorithm

Disclosed is a subroutine for a 16-bit floating-point square-root algorithm.
The implementation is for an 8-bit 8052 microcontroller and is based on the
Newton-Raphson approximation method [*]. The software is written in ASM51
microcode which is the assembly level microprocessor software language of the
Intel 8052 line of microcontrollers.

The advantage of the routine is its ability to obtain 16-bit floating-point
accuracy on an 8-bit microcontroller. The figure details the flow chart of the
algorithm.
